I don't know if I love the composition, or the focal point. Try lining them up so they're all pointed at the camera and then maybe focus on just the tips? Might be OCD or something, but it bothers me that they're not perfectly lined up. Also some of the colors clash...
If you want to experiment with it, and try different color combinations, this site may help guide you with what colors work together well:
Click where it says "complement" to see what colors complement one another.
